VALVE.

SPECIFICATION forming part 0f Letters Patent No. 675,622, dated J' une4, 1901.

Application filed September 10, 1900. Serial No. 29,540. (No model.)

To @ZZ whom, 'it mfr/J concern:

Be it known that I, WILLIAM J. CLINTON, a citizen of the United Statesof America, residing at Natrona, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inValves; and I do hereby declare the following to be a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to certain new and useful improvements in valves,and may be specifically designated as acid-valves,77 the same beingadapted to be used in that connection wherein the same comes intocontact with acids, and has for its object to construct a valve uponwhich the element-destroying properties of the acid will have no effect.

Brietiy described, the invention comprises a valve-casing having aninlet and outlet port, together with a valve-seat and a removabledisk-limiting standard or tube, together with the various details ofconstruction, as will be hereinafter pointed out.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate corresponding parts throughout theseveral views, in which- Figure 1 is a vertical sectional view of myimproved valve. Fig. 2 is a side elevation of the removable tube whichlimits the Inovement of the valve. Fig. 3 is a detail perspective viewof the plate which secures the said tube in position. Fig. 4c is adetail perspective view of the valve or valve-disk.

In the drawings, 1 indicates the valve-casing, which is provided with asuitable circular base 2, through which extends the inletport 3,communicating with the chamber a of the valve, and at one side of thecasing is an outlet-port 5, which also communicates with saidvalve-chamber 4,

Myimproved valve is preferably construct- 'ed of lead or like pliablematerial, the top of which may be bent over, as will now be described.

The ring G is placed over the valve-casing 1, as shown in Fig. l of thedrawings, and after being placed in this position the top of the casingis hanged outwardly, as shown at 7. This ring is provided with a seriesof circumferentially-arranged apertures 8, which are adapted to receivebolts 9, which also engage through apertures 10, provided therefor inthe securing-plate 11. This plate 11 engages the upper face of the plate12, which has secured to its underneath face a tube or post 14, having aplate 15 on its lower end. The base 2 is provided with a valve-seat 16inside the valve-chamber 4 and is adapted to have rest thereon asuitable valve or valvedisk 17, which is of a greater diameter than theplate 15. The acid is adapted to enter through the inlet-port 3, thepressure of the same unseating the valve or valve-disk 17 and allowingthe acid to pass up into the valvechamber and out through theoutlet-port 5. In event of back pressure through the outletport 5 thevalve or valve-disk 17 is immediately seated upon the valve-seat and theacid is prevented from passing downwardly into the inlet-port 3. Thetube 14 is for limiting the upward movement of the valve or valvedisk17, the plate 15, carried by said tube, affording such valve orvalve-disk a greater purchase and preventing the same being forcedupward in the chamber. It will be noted that when desired the tube maybe readily removed by loosening the bolts 9, which will permit theremoval of the plate 11.

Various slight modifications and changes may be made in the details ofconstruction without departing from the general spirit of the invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

The herein-described acid-valve, consisting of the casing 1, forming aninterior chamber 4, an inlet-pipe 3 entering the base of the saidchamber, a valve-seat 16, and disk valve 17, arranged at the entrance ofthe inlet-pipe, a ring 6 arranged over the casing 1, and the top of thesaid casing flanged over the said ring, a plate 12, orovided with adownwardly-projecting tube 14, to limit the upward movement of the valve17, a disk or plate 11, arranged upon the top of the plate 12, bolts 9',passing through the said ring, and plate to form a tight connection, andan outlet-pipe 5 5 entering the casing above the valve, all arl fixedmy'signature in the presence of two subscribing Witnesses.
